Abstract In the present article, I am examining, expanding, and re-evaluating a Lewinian kind of cultural psychology for cultural-psychological informed practitioners. Originating from field theory that behavior is function person environment, B(f) = P,E, introducing specific equation wanting to illustrate Lewin’s about psychology. A driven by needs goals develop while him relating his very own...

Given a C ? family of planar vector fields { X ? ˆ } ? W having hyperbolic saddle, we study the Dulac map D ( s ; ) and time T between two transverse sections located in separatrices at arbitrary distance from saddle. We show (Theorems A B, respectively) that, for any 0 L > , functions have an asymptotic expansion = ? with remainder being uniformly -flat respect to parameters. The principal par...

Cord blood (CB) provides an excellent alternative source of hematopoietic progenitor cells (HPC) for patients lacking human leukocyte antigen-matched peripheral blood or bone marrow graft for transplantation. However, due to the limited cell dose in CB graft, it is associated with prolonged time to engraftment, risk of graft rejection, infections, and treatment-related mortality. To increase th...

Students of social movements have long struggled with the question how relatively abstract political opportunities, such as elite divisions, affect unorganized activists without much knowledge of politics. We argue that the relationship between institutional opportunities and decisions to mobilize may take the form of trickle-down politics. In this view activists are affected by political oppor...

It has been known since Ehrhard and Regnier’s seminal work on the Taylor expansion of λ-terms that this operation commutes with normalization: the expansion of a λ-term is always normalizable and its normal form is the expansion of the Böhm tree of the term. We generalize this result to the non-uniform setting of the algebraic λ-calculus, i.e., λ-calculus extended with linear combinations of te...

We consider the question of when an expansion of a topological structure has the property that every open set definable in the expansion is definable in the original structure. This question is related to and inspired by recent work of Dolich, Miller and Steinhorn on the property of having o-minimal open core. We answer the question in a fairly general setting and provide conditions which in pr...

We compute an asymptotic expansion in 1/c of the limit in n of the empirical spectral measure of the adjacency matrix of an Erdős-Rényi random graph with n vertices and parameter c/n. We present two different methods, one of which is valid for the more general setting of locally tree-like graphs. The second order in the expansion gives some information about the edge of the spectrum. MSC 2010 C...

This paper presents a series expansion for the evolution of a class of nonlinear systems characterized by constant input vector fields. We present a series expansion that can be computed via explicit recursive expressions, and we derive sufficient conditions for uniform convergence over the finite and infinite time horizon. Furthermore, we present a simplified series and convergence analysis fo...

We combine several techniques to participate in Medical TREC 2011 and later we decompose our combined methodologies to gain a thorough understanding of the effects of each individual technique. In this paper we focus on Information Extraction and Expansion to find the best setting for an ideal IR system. Results suggest that Information Expansion is a key strategy in finding relevant reports fo...
